Abstract
A method and apparatus for detecting the orientation of each perforating gun in a wellbore and using that information in arming and firing each perforating gun in a perforating gun string.
Claims24
A perforating gun system comprising:
- a perforating gun string having at least one perforating gun, the perforating gun further comprising:
- a housing, a charge tube, a plurality of shaped charges, a detonator cord having a distal end and further coupled to the plurality of shaped charges, a detonator located proximate to the distal end of the detonator cord, an electronic switch having an onboard 3-axis accelerometer, wherein the switch is adapted to selectively address and initiate the shaped charges and activate and disarm a safety to disable detonator initiation based on orientation of the perforating gun detected by the accelerometer.
